What is a hiccup and why does it happen?!


Question: What is a hiccup and why does it happen!?
Answers:
Hiccups are sudden, involuntary contractions of the diaphragm muscle!. As the muscle contracts repeatedly, the opening between your vocal cords snaps shut to check the inflow of air and makes the hiccup sound!. Irritation of the nerves that extend from the neck to the chest can cause hiccups!.Www@Answer-Health@Com
